Abstract: An ophthalmological analysis instrument includes a first analysis apparatus for measuring a curvature of a cornea of an eye, such as a keratometer or the like, and a second analysis apparatus. The second analysis apparatus includes a projection device and a monitoring device. The projection device includes at least one slit projection unit for projecting a light slit onto a surface of the eye. An image of the light slit is recordable by the monitoring device, the light slit being projectable onto a region of a limbus of the eye by the slit projection unit. A topography of the surface in the region of the limbus is derived from the image of the light slit imaged on the surface.

Abstract: An ophthalmological analysis method measures an intraocular pressure in an eye using an analysis system. The analysis system includes an actuation device, with which a cornea of the eye is deformed contactlessly. The actuation device applies a puff of air to the eye to deform the cornea. A monitoring system monitors the deformation of the cornea and records sectional images of the undeformed and deformed cornea. An analysis device derives an intraocular pressure from the sectional images of the cornea, wherein the recorded sectional images of the deformed cornea are corrected relative to a recorded sectional image of the undeformed cornea, the intraocular pressure being derived under consideration of the correction.

Abstract: The invention relates to an ophthalmic analysis system and a method for measuring a geometry of an eye to be examined using the ophthalmic analysis system that comprises a first interferometric analysis system and a second non-interferometric analysis system. The first analysis system is used for obtaining measured data on optical boundary surfaces of the eye located on a measurement axis, and measured data describing relative distances, and the second analysis system is used for obtaining at least one set of image data on optical boundary surfaces located on the measurement axis. A processing device of the ophthalmic analysis system processes the measured data and the set of image data and corrects the set of image data using the measured data.
